KPH300 - Compact Pressure Switch

Brand: KOBOLD Instruments, Inc

The KOBOLD KPH300 compact pressure switch is an excellent choice for pressure switching applications that require a reliable yet low-cost solution.

The KPH300 uses proven diaphragm or piston-sensing technology, depending on the measuring range chosen.

The set point and hysteresis are field-adjustable via a 2mm hex nut adjuster protected from the elements beneath the DIN 43650 electrical connector.

The pressure switch can also be factory-set at the set point you specify.

The SPDT micro-switch contacts are silver-plated for extended service life.

The combination of high-reliability design and affordability makes the KPH300 an excellent choice for both OEM and industrial end-user applications.
